I am a Financial Time Series Analyst with an electronics engineering background, specializing in liquidity mapping, market structure annotation, and structured analysis of financial price data for research and quantitative use. My work focuses on converting discretionary market concepts—such as liquidity pools, sweep events, market structure shifts (BOS/MSS), and regime changes—into consistent, time-stamped datasets suitable for backtesting, research pipelines, and model training. I approach markets as engineered systems, applying disciplined signal-to-noise separation, rule-based logic, and repeatable annotation standards. Previously, I worked as a Field Service Engineer in the semiconductor industry, supporting complex electronic systems in production environments. This role required systematic fault isolation, analysis of logs and measurement data, and precise documentation under tight tolerances—skills that translate directly to financial time-series analysis and data labeling. I typically support quant teams, researchers, and technically oriented clients who need high-integrity datasets, clear rule definitions, and consistent handling of edge cases. I do not provide signals or discretionary trading advice; my focus is analytical, structured, and research-driven. If you need clean, well-documented market structure or liquidity datasets that your models can trust, I can help.
